【摘要】 用地震活动非均匀度GL值作参数,使用1980—2011年祁连山西端M≥3.0地震资料进行GL值的空间扫描。结果表明,祁连山地区74%的M≥5地震前1—2年,在未来震中周围均有GL值异常出现,用R值对其进行评分,可以通过检验。更多还原

【Abstract】 Taking the GL value,non-uniform seismic activity as parameter,the spatial scan of GL value on the data of earthquakes with M≥3.0 in the western end of Qilian from 1980 to 2011 was carried out.The results showed that for more than 74%earthquake with M≥5 in Qilian Mountains,GL anomalies appear around the potential epicenter before 1—2 year.This result has passed the test of R value grading.Typical example image shows the main characteristics.更多还原
